The invention relates to rail and flangeoilers and has as an object the provision of a simple device. foi applying lubricant'to the head. of a rail and/or the flange of a passing wheel.) Y It is an object of the invention to provide a device of this character which will be simple to manufacture ,andefficient in op eration.

To hold-the pistonin its normal positionshown in Figures 3 andfia spiral spring 37 seats upon the bottom end of the cylinder or upon the head 33 and acts in compression againstthe piston, sald spring be1ngcom pressible when the flange of a wheel,'as indicated in Figure 4, comes 'intocontact with the projecting upper end of the piston.

To conduct lubricant from the passage 29 to the chamber 31, and thus to the cylinder below the piston through the passages 35,

, there is shown a passage 38 normally inv registry with the passage 29, as shown in Figure 3, but removed from such communication when the piston is depressed. $uch depres sion of the piston-also closes the passage 38 by lowering thesame below the upper'end of the's'tem 34, r

2A secondpassage in thepiston 26' is shown a539- placing the chamber 31in communication with the cavity 30. An outlet passage 40 is shown through the body of thepiston,

itslower end being normally out of registry with the cavity andits upper end being- V cavity 30and theconsidera-ble pressure thus suddenly applied upon the piston and thus uponthe confined lubricant will cause a jet of lubricant tov flowinto the angle between the wheel flange and the head of the rail.

. i tueof the closing of both endsof cant will be forced back into the pip'e'QO the passage 38 by its movement out of regisr try with the passage 29 and to'a position-op,

'posite', the stem 34, a double closure of the passage 38 will result to ensure that no lubriagainst the pressure therein, the pressure pro;

duced in the cylinder being considerably greater 1 than that normally present in the receptacle 12. i a In the form of the invention shown in Fig- I 6 ure 6 the passage 38' normally opens into the cylinder 25 below .the piston26 and; in a position to be immediately closed by the piston when depressed. The piston is held norjmally at its upper position determined, by

stop' screw 27 entering cavity 28- in the piston, byexpansible spring 87. A cavity 45 is I shown in thewall of the lower portion of the V 7, cylinder to perform the function of cavity 30 'in the formof F i'gures 1 to 5. The cavity- 2 5 may be madeof such a depth that the p'assage lO communicating with its inner end Wlll have such a d rection as to deliver the lubricant to thedesired point upon the rail head or wheelflange or both. In this form of'the inventiondepression of the piston willclose passage38 and afterward bring cavity 28' into communication with cavity 15 to cause lubricant to flow'from the cylinder 25 below the piston through the cavities and out through passage 40';

Thedevice is particularlyadaptable to application upon rail curves and being readily connected up in multiple, so many thereof as cant receptacle 12 to oil a passing wheel at several points in its revolution upon the rail 10 as well as to oil spaced portions of the rail head. There being but one movable part,

namely, the piston 26, with no spring pressed valves, the devices is little liable to derangement and is very simple to manufacture and assemble.
